Popis: The aim of this study was to assess volumetric imaging dose and image quality during radiotherapy in case of Hodgkin lymphoma. The absorbed doses were measured using ionization chamber in thorax phantom. For the same setup, Monte Carlo simulations were performed. The image quality was assessed using Catphan phantom. The absorbed doses ranged from 4.4–7.7 mGy (full rotation) and 1.1–3 mGy (partial rotation). Doses from simulation ranged from 6.8–15.6 mGy (full rotation) and 1.9–10.4 mGy (partial rotation). The image quality tests have shown differences between clinical protocols. The imaging doses were smaller than prescribed doses, but shouldn’t be neglected. © 2021, Publishing House of the Romanian Academy. All rights reserved.
